So there is a treat i remember my mom used to give me when i was growing up in the 1990s. I was born in Seattle, but moved to London in like 1998 so i dont remember if this treat was American or English, but here i go;

It came in multipacks of like 10
They were like jello, but they were small, like the size of a base of a drinking glass
They were colored
They were in individual packets, which were like semi circles, and the outer side you pop through, breaking the seal, and then you could eat it/

jello shots?

Interesting.

I think I remember seeing an ad for the product that Braken is looking for.  They were non-alcoholic.  But the fact that a company existed and sold pre-packaged jello shots indicates that this form of food still exists.

There's also this link to a bag of Gel Bites, indicating non-alcoholic jello snacks still exist, but these aren't the things Braken's looking for.  I could be wrong, but vaguely recall something that resembled a small ice cube tray.  (Each jello snack was about the size of the "shots" shown above.)
